IIEPROVED MATERIAL FOR JOURNALS AND BEARINGS, FOR LUBRICATING.

The Schedule referred to in these Letters Patent and making part 0! thename To whom it may concern:

Be it known that I, A. B. JONES, of Wilmington, in the countyof Hanover,and State of North Carolina, have invented certain new and usefulImprovements iir-Lubricating Compounds; and I hereby declare thefollowing to be a. full, clear, and exact description of the same.

The nature of my invention consists in the employment as a lubricatingagent of disintegrated vegetable fibre, preferably that of the bamboo orcane, disintegrated by the explosive force of steam, in accordance withthe process described in Letters Patent granted to A. S. Lyman, underdate of 3d August, 1858, in combination 'with oil, or equivalent, inlieu of the means ordinarily employed for the purpose.

Cotton-waste, which is now so generally used in stuffing andjournal-boxes, is objectionable onmany accounts, as it burns outrapidly, consumes much oil, and is in itself expensive. I have found, bycareful and continued experiments, that the disintegrated fibreaforesaid, which first having been divested of its silicious coating, bythe steam-blowing process, is then dusted and freed from extraneousmatter, by means of a fan, or by other suitable means, is a much bettermaterial on all accounts. lVben used, for instance, in

the journal-box of a car-truck it will remain unimpaired fora length oftime in which the cotton-waste, if it were employed, would need to berenewed two or three, or more times.

It also requires a less frequent application of oil, retaining anddistributing the oil, or other lubricant, much better than the ordinarymaterial, and being free fromthe silex contaiuedby vegetable matter inits ordinary condition, and which would impair its absorbent andlubricating qualities, and being moreover soft, pliable, and perfectlydisintegrated, it is perfectly adapted to the uses for which I designit, and can be employed to advantage in stuffing-boxes of steam-engines,in journal-boxes, and, in fact in all instances, where a lubricator isrequired.

The first cost of the fibre is much less than that of any materialheretofore employed, and in this respect alone, its employment isproductive of advantages. I may add also, that the fibre, while fittedfor use in the condition in which it comes from the steam-gun, may, ifdesired, be subjected to further treatment, such as washing, pressing,850., sons to more thoroughly rid it of all extraneous matter, but inpractice this will hardly be found necessary.

Having now described my invention, and the manner in which the same isor may be carried into effect,

What I claim, and desire to secure by Letters Pat.- ent, is

The employment, for-lubricating purposes, of vegetable fibre,disintegrated by the explosive force of steam, in combination with oil,or other suitable lubricant, substantially herein specified.

In testimony whereof, I have signed my name to this specification,before two subscribing witnesses.

A. B. JONES.
